GRAPEVINE Phenological stage: berries pea-sized- beginning of bunch closure
Mildew:Ver Fotos

The situation of grapevines has slightly improved as compared to previous weeks, and no new symptoms appeared in untreated control plants. However, it must be remarked that after last infections, many grapevines showed affected berries. If North winds persist, grapevine conditions will be improved, but it is necessary to keep the maximum level of surveillance because any change in the weather conditions will lead to the emergence of new symptoms.

Oidium:Ver Fotos

No symptoms have been observed along this week. However, grapevine is initiating the stage "bunch closure", highly sensitive to the disease, thus monitoring should be increased.

Black-Rot: Ver Fotos

The situation in our monitoring plot has improved, being highly favoured by the change in the environmental conditions. Control plants did not show new signs of the disease. Sheet

Moths:Ver Fotos

Lobesia botrana - Grapevine moth penetrationMoth captures in the traps have been low. However, first signs of larval activity are observed. Monitoring should be increased, but so far it is not necessary to treat.

Green mosquito and other cicadellidae:Ver Fotos

Cicadellids- Zygina rhamni adult on leaf underside. The number of captures in the traps has increased, mainly of Zygina rhamni, species with nymphs on the leaves. The evolution of populations should be monitored.

Mites:Ver Fotos

Calepitrimerus vitis - Acariose first symptomsSigns of mite feeding activity have been observed again in untreated control plants. Temperatures are expected to rise, which will make it necessary to increase monitoring since these animals develop better in warm and dry conditions.

Wood diseases:Ver Fotos

Eutypa and Esca complex - Plant symptomsDuring these days, we are beginning to observe plants with symptoms of any wood disease. We must remark that these plants should be marked to differentiate them from the other plants so as to take the appropriate measures.

Scab:Ver Fotos

In general, we have not observed any symptoms of the disease during this week, not even in most sensitive varieties.

Cydia pomonella:Ver Fotos

We haven't recorded any adult captures in any of the traps placed in our monitoring plots. However, environmental conditions expected for the following days favour pest development, thus we must check plants for the manifestation of signs of larval penetrations into the fruit, or treat in case a specific monitoring is not being performed.

Red spider:Ver Fotos

We must remark that in case a previous treatment had been performed to reduce mite populations, its efficacy must be confirmed, since we have received previously treated plant samples with mite populations. In addition, expected weather conditions favour the dissemination of the pest.


Toxoptera aurantii colony on lemon tree shootColonies of different aphid species are being observed again in both fruit and horticultural crops. High temperatures favour the establishment and development of the insect. Thus in case they are observed, plants must be treated as soon as possible.
